I received mine yesterday and was playing around with the castle link. Why does it let you choose lipo cutoff over 2S (6V). It leads me to believe you can put a 3S or 4S battery on the ESC?
Mine seemed to have a fair bit of go. I'm using a 3300mah 2S 45C pack. Maybe a lower C rating is limiting ev01's?
I would not exceed 3s LiPo on it. I didn't have any issues with running it on 3s for extended periods of time.
